“…Fish muscle is remarkably plastic in its response to changes in environmental conditions, primary among which is temperature (Johnston, 1993;Johnston, 2001;Johnston et al, 1998;Martell et al, 2006). This plasticity often involves directional changes in the number and size of red and white myofibres (Johnston, 2001;Stoiber et al, 2002;Johnston and Hall, 2004), changes in the frequency (Johnston, 2001) and periodicity of each type of myofibre recruitment (Brodeur et al, 2003;Johnston, 2006), and changes in the myogenic progenitor cell populations (Johnston, 2006).…”

“…This plasticity often involves directional changes in the number and size of red and white myofibres (Johnston, 2001;Stoiber et al, 2002;Johnston and Hall, 2004), changes in the frequency (Johnston, 2001) and periodicity of each type of myofibre recruitment (Brodeur et al, 2003;Johnston, 2006), and changes in the myogenic progenitor cell populations (Johnston, 2006). At the cellular level, changes in temperature may also bring about variation in myofibril (Johnston, 2001;Johnston, 2006;Martell et al, 2006) and mitochondrial densities (Johnston, 1993;Galloway et al, 1998;Sänger and Stoiber, 2001;Johnston and Hall, 2004). Minor shifts in temperature have been shown to have significant effects on development in rapidly growing embryonic and larval phases (Blaxter, 1992;Kamler, 1992;Johnston, 2001;Johnston, 2006;Johnston and Hall, 2004) such that temperature variation during embryogenesis can differentially affect fast and slow muscle development and growth (Johnston et al, 1998;Stoiber et al, 2002;Johnston and Hall, 2004;Johnston, 2006).…”

“…Studies have also revealed that these changes can persist through ontogeny, affecting subsequent production of somatic tissue (i.e. growth) (Johnston and Hall, 2004;Martell et al, 2005;Martell et al, 2006), swimming style, and performance Johnston and Temple, 2002;Johnston and Hall, 2004;Johnston, 2006). For example, increased incubation temperature affected the time taken to complete metamorphosis and the proportion of muscle fibre types present in the postmetamorphic juvenile turbot (Scophthalmus maximus L.) (Calvo and Johnston, 1992).…”

“…Fewer still are studies that have controlled for post-hatch temperature conditions to examine the ramifications of temperature differences during embryonic development (Johnston, 2006). From our previous studies of haddock development over different temperatures, it is clear that incubation temperature affected general developmental rates, tissue-specific development, yolk absorption and growth (Martell et al, 2005;Martell et al, 2006), and that these effects persisted throughout larval and early juvenile phases. These changes may have a large potential impact upon larval function and capability (i.e.…”

Muscle development and growth were investigated in haddock larvae(Melanogrammus aeglefinus L.) incubated under controlled temperatures(4, 6, 8°C) and reared post-hatch through yolk-dependent and exogenous-feeding stages in a 6°C post-hatch environment. Changes in cell number and size in superficial and deep myotomes within the epaxial muscle were investigated for 28 days following hatch. Distinct and significant differences in muscle cellularity following separate developmental strategies were observed in superficial and deep myotomes. The number of superficial myofibres increased with time and, although not in a manner proportional to temperature during the first 21 days post hatch (d.p.h.), there was observed a trend during the final 7 days of greater mean cell size that was strongly associated with increased temperature. In addition, there was an apparent correspondence between increased temperature and increased size between 21 and 28 d.p.h. Among all temperature groups the superficial myotome not only demonstrated a consistent unimodal myofibre-size distribution but one that increased in range proportional to temperature. In the deep muscle, myotomes from higher incubation temperatures had a broader range of fibre sizes and greater numbers of myofibres. The onset of a proliferative event,characterized by a significant recruitment of new smaller myofibres and a bimodal distribution of cell sizes, was directly proportional to incubation temperature such that it occurred at 14 d.p.h. at 8°C but not until 28 d.p.h. at 4°C. The magnitude of that recruitment was also directly proportional to temperature. Following hatch, those embryos from the greatest temperature groups had the largest mean deep muscle size but, as a result of the proliferative event, had the smallest-sized cells 28 days later. The muscle developmental and growth strategy as indicated by sequential changes in cellularity and cell-size distributions between myotomes in response to temperature are also discussed in light of whole animal growth and development.

Short- and long-term effects on growth and expression patterns in response to incubation temperatures in Senegalese sole

et al. 2018

In this study, the short-and long-term effects of embryo incubation temperatures (16, 18 and 20ºC) on development and growth of the flatfish Senegalese sole (Solea senegalensis) was determined by investigating the expression patterns of the epigenetic regulators DNA methyltransferases (dnmt) and histone 3 (H3) and genes belonging to the retinoic acid (RA), insulin-like growth factors (IGFs) and hypothalamic-pituitary-thyroid (HPT) axes. Results indicated that egg incubation temperature affected embryo development, but not survival, and incubation at 16ºC significantly delayed development. Coincident with these effects, levels of muscle-specific dnmt3aa transcripts and histone H3 protein levels were significantly different between the 16 and 20ºC groups at hatch. The larvae from eggs incubated at 20ºC relative to the 16ºC group had significantly higher transcript levels of four genes belonging to the HPT axis (trhr1a, tshr, thrb and dio2), four genes of the RA axis (aldh1a2, cyp26a1, rara2, rarg), igfbp1 and the glycolytic enzyme gapdh2. Taken together the data suggest that higher egg incubation temperatures enhance energy production, which accelerates cell proliferation and larval development and that hatching is a key moment for the regulation of epigenetic mechanisms.Long-term effects of egg and larval incubation temperatures were revealed by a higher mRNA abundance of the thyroid-related genes tgb and tpo and the RA degrading enzyme cyp26a1 in preand metamorphic larvae when they were incubated at 20ºC as embryos and may be related to the earlier initiation of metamorphosis in the pelagic larval stages. Evaluation of growth in pelagic larvae and juveniles after weaning (one trial from 42 to 119 and another from 164 to 247 days post-hatch using a longitudinal approach) revealed that juveniles from embryos incubated at 20ºC had a higher growth rate. All these data demonstrate that the thermal regime during embryogenesis modulated mechanisms that regulate larval plasticity and caused imprinting evident in juvenile sole as persistent changes in key endocrinological pathways and growth performance.
